Bookkeeping Basics for Tradespeople: A Plain-English Setup Guide

If you swing a hammer, run wire, or unclog drains for a living, you probably didn't get into the trades to do paperwork. But the contractors who keep clean books are the ones who sleep at tax time, qualify for loans, and actually know whether last month made money. Good news: bookkeeping for a one- or two-person trade business isn't complicated. You don't need an accounting degree or expensive software. You need a handful of habits and about 30 minutes a week.

This guide walks through a practical system from scratch: separating your money, tracking what comes in and goes out, logging miles, invoicing so you get paid, watching cash flow, and setting aside enough for taxes. Pick the pieces you don't already have in place and build from there.

Start with one move: a separate business bank account

This is the single highest-leverage thing you can do, and it's free or nearly free. When your business income and expenses run through their own checking account, your bookkeeping is half-done before you start. No more untangling whether that Home Depot run was for a job or for your own garage.

Open a business checking account (most banks and credit unions offer one for low or no monthly fees if you keep a small balance). Then:

• Run every dollar of job income into that account.
• Pay for every business expense — materials, tools, fuel, insurance, subscriptions — from that account or a dedicated business card.
• Pay yourself by transferring money to your personal account. That transfer is your 'paycheck,' and it keeps the line clean.
• Never put personal groceries or your kid's soccer fees on the business card. Mixing the two ('commingling') is what turns a 20-minute month into a weekend of detective work.

If you've formed an LLC or corporation, a separate account isn't just convenient — keeping business and personal money apart helps preserve the liability protection the entity is supposed to give you. Talk to your attorney or CPA about your specific structure.

Track income and expenses as you go, not in April

Bookkeeping is just two questions answered consistently: what came in, and what went out. The trick is recording it close to when it happens, while you still remember what that $86 charge was for.

Capture every receipt

Snap a photo of paper receipts the moment you get them, then toss the paper. Most accounting apps and even free note apps let you store images. For digital receipts, forward the email to a dedicated folder. The IRS generally expects you to keep records that support your income and deductions, and a clear receipt beats a fuzzy memory every time.

Sort expenses into simple categories

You don't need 50 categories. A trade business usually fits into a dozen or so. Start with:

• Materials and supplies (lumber, fittings, paint, parts)
• Tools and equipment
• Vehicle and fuel
• Insurance (general liability, workers' comp, commercial auto)
• Licenses, permits, and bond fees
• Subcontractor or helper pay
• Phone, internet, and software
• Marketing and platform/membership fees
• Office and admin (printing, bank fees)

Consistent categories make it obvious where your money goes and feed straight into your tax return at year-end.

Keep a mileage log — it's real money

Driving between jobs, to the supply house, and to estimates adds up fast, and business miles are one of the most valuable deductions a tradesperson has. But the deduction only counts if you can back it up with a log.

For each business trip, record the date, where you went, the business purpose, and the miles. A phone app that auto-tracks drives is easiest, but a notebook in the truck works too. Note your odometer reading at the start of the year and the end so you can show total vs. business miles. The IRS sets a standard mileage rate each year (it changes annually), and you can usually choose between that rate or tracking actual vehicle costs — but you need records either way.

Invoice clearly so you actually get paid

Money you've earned but haven't collected isn't money in the bank. Clean invoicing shortens the gap between finishing work and getting paid. A solid invoice includes:

• Your business name, license number, and contact info
• An invoice number and date
• A clear description of the work and materials
• The amount due, deposit or progress payments applied, and the balance
• Payment terms (for example, 'Due within 7 days') and accepted payment methods

Send invoices the day the work wraps, not a week later — promptness sets the tone for prompt payment. For larger jobs, structure payments in stages (deposit, progress, final) so you're never floating thousands in materials on your own dime. On LocalFixx, quotes, messaging, and secure payment all happen in-app, so the homeowner sees the price you set and pays through the platform — less chasing, fewer awkward 'did you get my invoice?' texts.

Watch cash flow, not just profit

Plenty of busy trade businesses run short on cash even while they're profitable on paper. The culprit is timing: you buy materials today and get paid in three weeks. A few habits keep you ahead of it:

1. Collect a deposit before you buy materials for a job, so a customer's project funds itself instead of draining your account.
2. Send invoices immediately and follow up on anything unpaid past your terms.
3. Keep a small cushion — even one to two weeks of operating costs — so a slow week or a late-paying client doesn't stall you.
4. Glance at your business account balance and outstanding invoices weekly. Thirty seconds of awareness prevents most cash crunches.

Set aside money for taxes every time you get paid

When you're self-employed, no one withholds taxes for you. You're responsible for income tax plus self-employment tax (which covers Social Security and Medicare), and most self-employed folks who expect to owe are required to make estimated tax payments quarterly rather than once a year.

The simplest habit: every time a payment lands, move a percentage straight into a separate 'taxes' savings account and don't touch it. A common rule of thumb is to set aside somewhere around 25–30% of your net income, but the right number depends on your total income, deductions, filing status, and state. Treat that account as money that was never yours.

Mark the quarterly estimated-payment deadlines on your calendar so they don't sneak up on you. A CPA can tell you exactly what percentage fits your situation and whether quarterly payments apply to you — that one conversation often pays for itself.

Spreadsheet or software? Both can work

Don't let tool choice stop you from starting. The best system is the one you'll actually keep up with.

A simple spreadsheet

If you're just starting out or doing a handful of jobs a month, a spreadsheet is plenty. One tab for income (date, customer, job, amount), one for expenses (date, vendor, category, amount), and one for mileage. Total each column monthly. It's free, it's yours, and it teaches you exactly where your money moves.

Accounting software

As your volume grows, software that connects to your business bank account can auto-import transactions, let you snap receipts, send invoices, track mileage, and produce reports your accountant will love. Expect to pay a modest monthly subscription. The time it saves — and the deductions it helps you capture — usually justifies the cost once you're running steadily.

A reasonable path: start on a spreadsheet, and graduate to software when manual entry starts eating real time or when you hire help. Either way, reconcile against your bank statement once a month so your books match reality.

Your 30-minute weekly routine

• Import or enter the week's income and expenses, with receipts attached.
• Log any business miles you haven't recorded.
• Send invoices for completed work and follow up on overdue ones.
• Move your tax percentage into the tax savings account.
• Glance at your balance and outstanding invoices.

Do that every week and tax season becomes a non-event instead of a fire drill. You'll also be able to answer the question that matters most: am I actually making money, and on which kinds of jobs?
